Q1: What does “safely split a string into an array” mean in Bash? A1: In Bash scripting, "safely splitting a string into an array" refers to the process of breaking down a string into multiple elements based on a specified delimiter while avoiding issues like word splitting and globbing. This ensures that each component of the string is treated as a separate item in an array, without unintended alterations.
